Relay Automotive Procurement Notes

Verify that the specific suffix 'R' corresponds to the required packaging format, as datasheets may list tray packaging for the base part number. Confirm that the 24 VDC coil voltage aligns with the target system's power supply requirements. Ensure the through-hole mounting style and PC pin dimensions are compatible with the intended PCB layout. Check for any specific environmental certifications or compliance documentation required for the final assembly.

Relay Automotive Selection Notes

Select this component when a 30 A SPST-NO automotive relay is required for 24 VDC control circuits. The A6 series is suitable for high-current switching in harsh environments due to its wide operating temperature range. Consider the 5 ms operate time and 2 ms release time for timing-sensitive applications. Verify that the 1.3 W coil power consumption fits within the available driver capacity.

Relay Automotive Part Context

This relay belongs to the CIT Relay and Switch A6 series, which is specifically engineered for automotive and heavy-duty applications. The series includes various coil voltages and contact configurations to support diverse industrial needs. The A61AS variant denotes the SPST-NO configuration within this lineup, providing a robust solution for switching high-power loads in vehicles and machinery.

Relay Automotive Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other CIT A6 series relays if different coil voltages or contact forms are needed. Verify mechanical footprint compatibility before substituting with relays from other manufacturers.
